javascript - GWT: com.google.gwt.core.client.JavaScriptException. only using Internet Explorer -

Before explaining my problem, I must say that my GWT version is 2.2.0 and the error is only used when Happens when i Internet Explorer (IE 8 in this case)

I have a small GWT project that throws a button the next method:

  Private zero expotarExpediente (VistaExpediente Vista) { Last String Template URL = GWT.getHostPageBaseURL () + "Export? Id =" + vista.getId (); Window.Open (Template URL, "Explorer's Explorer Expands:" + Vista. NewswereexDentain ("," "); }   
 This method creates a template URL to call the classic HTTPServlet ("Exporter"), which generates a ZIP file for users to download. Sentence window Open a window in the Open (...) browser that allows to download the file.  
 It works properly in all browsers except Internet Explorer. Thrown exception is beside: 08: 31.208 [error] [sistmedfiniciontramites] Exempt exceptions dropped out com.google.gwt.core.client  
 Exception exception Next

 I do not find any decent solution for searching by Google. I would like to know if anyone had this problem before Or there is such a problem and if he can remove it.  
 Thanks and sorry for my bad english.  
  
 
 
 Internet Explorer does not like the blank space in the name of the window when calling  window .open () . Then your string:  
  "Explorer's Explorer Address:" + vista.getNumeroExpediente ()   
 should be without spaces.
